Van Dyke Brown Printing Setup for Beginners

Cyanotype Has a Moody Older Sibling

Van Dyke brown belongs to the same family of sunlight printing that gave us cyanotype's famous blue, except the finished image is built from real silver and comes out a deep, velvety sepia. You brush a straw-colored solution onto paper in a dim room, press a negative against it under glass, and let the sun draw the picture while you watch it darken. The process descends from the argentotype that astronomer Sir John Herschel worked out in 1842, yet its name honors no photographer at all: it's borrowed from Anthony van Dyck, the Flemish painter whose brown paint the prints happen to match. Printers still call it the poor man's platinum.

This page assumes you've already sunned a print or two. Van Dyke rewards people who arrive from a beginner cyanotype setup: coating paper, guessing an exposure, rinsing in a tray, all of it transfers straight across. What changes is the chemistry shelf. There are three solutions instead of one, a fixing bath the blue process never needed, and a bottle of silver nitrate that demands actual respect. If you've never coated a sheet in your life, go make blue prints first; this page will still be here.

The upgrade path is short on purpose: three chemicals, a block of cotton paper, and a jar of fixer are genuinely the whole ask, because your brush, glass, and trays carry over from the blue process.

Prices below were picked with the second-process reality in mind: the silver is the splurge, so everything around it stays deliberately cheap.

Three Bottles, a Fix, and Honest Paper

The heart of the process is a sensitiser you mix yourself from three cheap solutions: ferric ammonium citrate, tartaric acid, and silver nitrate, each dissolved in distilled water. Combine the first two, then add the silver slowly while stirring, and store the lot in a brown bottle somewhere dark. Give it a couple of days to rest before the first print. Freshly mixed sensitiser prints noticeably worse, and a rested bottle keeps for months. Coating is the same dance you know: one thin, even pass in dim light, then dry the sheet flat in the dark. If the paper curls, you've used too much.

Gear That Buys You Repeatability

Nothing in this section is strictly required. The glass and clips that exposed your first cyanotypes will expose brown prints too. But Van Dyke exposures run longer and punish sloppy contact harder, so these upgrades earn their keep faster than they did with blue prints. My order: gloves first (honestly the one thing here I wouldn't skip), then the frame, then the lamp once autumn starts cancelling your printing days. The transparency film quietly changes what the hobby is. Suddenly any photo on your phone can become a small brown print with real silver in it.

Read This Before You Open the Silver

Silver nitrate is the one item on this page that will punish carelessness. On skin it leaves no burn you'll feel right away; instead the spot quietly turns brown, then black, and the stain wears off only as the skin itself does, over days. At working strength it's corrosive, and a splash in the eye is an emergency. Wear the nitrile gloves from the list above every time the bottle is open, and glasses if you have them.

The sneaky part is that spills are invisible at first. A stray drop on the bench or a doorknob shows up tomorrow as a black fingerprint you can't remove, so wipe the work area down while you still remember where you worked. Keep the crystals and the mixed solution in the dark, label every bottle, and keep all of it away from kids and pets. The other chemicals are mild by comparison, but the same habits cost nothing.

When Brown Prints Go Wrong, They Go Wrong Three Ways

Why did my print fade or go patchy a few days after I made it?

Almost always this is chemistry left behind in the paper, and beginners fall into it because the print looked finished when wet. Leftover iron or fixer keeps working after you've framed the print, eating the silver image from inside. The fix is boring and absolute: use unbuffered cotton paper, wash generously before and after a weak fixing bath, and let a hypo-clearing bath of sodium sulfite shorten the job. A print that's truly clean stays brown for decades.

Why are my highlights muddy instead of clean paper-white?

Muddy highlights are fog, and fog means light got where it shouldn't. Coating in a bright room, drying the sheet in daylight, or simply overexposing all leave the whites dirty, and beginners usually blame the chemistry instead. Coat and dry in genuinely dim conditions, and pull the frame while highlights still look yellow; they'll deepen in the fix. If whites still won't clear, your coat is going on too thick.

What are these yellow stains that showed up after washing?

Yellow blotches are fixer residue, and cotton rag holds onto it stubbornly. A quick rinse feels sufficient because the print looks clean, but the stain develops later as the residue breaks down. Give the final wash a full half hour in gently running water, and add a sodium sulfite clearing bath before it; a spoonful per litre is enough. Papers this thick simply drink more than glossy darkroom paper ever did.

Why does the print look wrong straight out of the wash?

Because you're not looking at the finished print yet. Van Dyke shows only about half its final depth during exposure, darkens dramatically in the fixer, then shifts again as it dries down overnight. Beginners chase the wet image, re-exposing or re-fixing a print that was actually fine. Judge exposures only against dried results, and write the time on the back of every sheet so tomorrow's print can learn from today's.
